Explanation

OTV (Overlay Transport Virtualization) requires an OTV Edge Device in each participating data center. This device is responsible for encapsulating and decapsulating L2 frames into the OTV overlay and exchanging MAC reachability information between sites via the IS-IS-based OTV control plane. It functions as the tunnel endpoint for the OTV overlay - conceptually analogous to a VTEP (VXLAN Tunnel End Point) in VXLAN deployments. VXLAN itself is a separate technology; each DC in an OTV deployment needs at least one OTV-capable edge device to join the overlay.
